Unfortunately I don't think a line will work. The boundary detection handles ellipses (circles really, equal height and width), rectangles, and convex polygons. The closest you could come to a line is a very skinny rectangle :)

Farseer 3 itself could create lines, you would just need to call the Farseer classes directly without using the Physics Helper.

However i have a new problem of adding it back. Even though i add it through code like i did previously, its still not getting added as a physics object. Maybe some issue with Object Name. Still looking into this.

Is there any better way of doing this? I want to change the coordinates of the line and it should still behave like a physics object.

If i directly change the coordinates of the line, the UI line changes but an invisible physics line gets left behind at its previous position. Please help me.
